The objective of this symposium is to address the materials and mechanisms of correlated electronic phenomena that arise in artificial transition-metal oxide (TMO) heterostructures due to strong electron-electron and/or electron-lattice interactions. Heterostructures and multilayers with atomically abrupt interfaces between complex TMOs are becoming available as a result of recent developments in thin-film-fabrication techniques. Such synthetic structures display properties that are dramatically different from those of the constituent oxides in their bulk forms. Advanced microscopy and spectroscopy techniques enable fundamental understanding of such heterostructures; particularly the emergence of novel electronic, magnetic, photonic and topological phenomena driven by correlation effects, broken symmetries, interfacial doping and interface induced structural modifications. Correlated electrons in TMO interfaces often induce metal-insulator transition, superconductivity and magnetism. These phase transitions can be tuned by external stimuli such as electric and magnetic fields and pressure, which makes oxide interfaces particularly interesting not only from the point of view of basic science but also as important ingredients in novel electronic devices. Of particular interest are digital interfaces that can be used in future applications such as spin-controlled electronics (spintronics) and quantum computation. Other fascinating examples are interfaces where multiple orders may coexist such as superconductivity with magnetism resulting in an exotic symmetry of the superconducting order-parameter, and ferromagnetism with ferroelectricity with a significant degree of coupling between the two order parameters. Interface designs have proven critical in enhancing macroscopic interdependent orders and their tunability. In addition to widely-studied 3d TMO heteostructures, 4d, 5d and 4f systems are also covered. In these systems, one could even anticipate novel phenomena due to the increased spin-orbit coupling, which competes or cooperates with correlation effects.
